Well I just fired her up at 12 below. No problellm starting, but Idon't imagine the neighbors appreciated the diesel cloud. I let her run a couple minutes then shut her off and plugged her in tosee what happens in while. And the old plugs would light for about an inch als.l

I haven't yet tried tuning anything with the air intake heater but I will see if I can't do something with it and get it to turn on once the glow plugs turn off....usually, it's commanded after a couple minutes of idling but if it can be commanded sooner and during warm up, I'll let you know and maybe you can get Bill to incorporate that into your tunes.

But then again, maybe Bill will read this and know the answer already.

I also found out that if I leave it plugged in that it won't smoke on start up. I am thinking maybe averything just might be normal, a COLD diesel. Thanks for everything so far guys. It's nice to have a little help figuring things out sometimes.
